S2000-UV-VIS Spectrometer

The S2000-UV-VIS Miniature Fiber Optic Spectrometer is a low-cost, general-purpose instrument for absorbance, reflectance and emission measurements.

The S2000-UV-VIS is no longer available. It has been replaced by the far more advanced and compact USB4000-UV-VIS Spectrometer.

The S2000-UV-VIS spectrometer is pre-set to a 200-850 nm wavelength range and comes with a UV2 Detector Upgrade, multi-bandpass order-sorting detector coating and 25 mm entrance slit for high-resolution (to 1.5 nm FWHM) performance. Operating software is included.

The S2000-UV-VIS Spectrometer features a compact optical bench coupled to a 2048-element linear CCD-array detector. The spectrometer accepts light energy transmitted through single-strand optical fiber and disperses it via a fixed grating (set for 200-850 nm) across the CCD array. An SMA 905 connector allows for easy coupling to Ocean Optics' comprehensive line of fiber optic light sources and accessories.

The S2000-UV-VIS can be used with a desktop PC via Ocean Optics' ADC1000 ISA-bus A/D converter.

S2000-UV-VIS Fiber Optic Spectrometer -- Specifications

Ocean Optics miniature fiber optic spectrometers offer high performance at low cost, in a convenient, modular package. Optical performance varies according to a number of factors, including the grating's groove density and the entrance optics' size -- as well as the application itself (for example, low vs. high light level applications).
